Donovan (concussion) hasn't been cleared to return to action yet, Ryan Divish of The Seattle Times reports.
Donovan has still felt concussion symptoms like nausea, fatigue and dizziness while participating in pregame workouts, and he will not be cleared to play until he can make it through a whole pregame workout without symptoms. The 29-year-old has been sidelined since he was hit in the head by a baseball in the batting cages pregame Aug. 22 against the Cubs.
